usa259 Posted March 17, 2015 Share Posted March 17, 2015 I'm considering trying IDPA and I'm learning about my new P320 and was thinking I would be entering Stock Service Pistol (SSP). My P320 is chambered in 40 S&W and I've been learning about creating a load for it with a Power Factor of about 135. It has been suggested that with a 135 Pf i would probably need to change the guide rod and spring from aftermarket supplier and the spring would be of lighter duty. If I were to change to the suggested guide rod and spring would this eliminate me from SSP? I copied this rule from another thread: 8.2.1.3.4. Recoil spring guide rods and dual spring recoil systems made of material that is no heavier than stainless steel. Thanks you,Chris Link to comment Share on other sites More sharing options...
Marshal82 Posted March 17, 2015 Share Posted March 17, 2015 Nope you will stay in SSP just fine. Just don't use a tungsten guide rod. Link to comment Share on other sites More sharing options...
